Anti-American sentiment and America's perceived intent to dominate: An 11-nation study

Perceptions of America as a powerful but malevolent nation decrease its security. On the basis of measures derived from the stereotype content model (SCM) and image theory (IT), 5,000 college students in I I nations indicated their perceptions of the personality traits of, intentions of, and emotional reactions to the United States as well as their reactions to relevant world events (e.g., 9/11). The United States was generally perceived as competent but cold and arrogant. Although participants distinguished between the United States' government and its citizens, differences were small. Consistent with the SCM and IT, viewing the United States as intent on domination predicted perceptions of lack of warmth and of arrogance but not of competence and status. The discussion addresses implications for terrorist recruitment and ally support.

Conservation and accessibility of an inner core lipopolysaccharide epitope of Neisseria meningitidis

We investigated the conservation and antibody accessibility of inner core epitopes of Neisseria meningitidis lipopolysaccharide (LPS) because of their potential as vaccine candidates. An immunoglobulin G3 murine monoclonal antibody (MAb), designated MAb B5, was obtained by immunizing mice with a galE mutant of N. meningitidis H44/76 (B.15.P1.7,16 immunotype L3). We have shown that MAb B5 can bind to the core LPS of wild-type encapsulated MC58 (B.15.P1.7,16 immunotype L3) organisms in vitro and ex vivo. An inner core structure recognized by MAb B5 is conserved and accessible in 26 of 34 (76%) of group B and 78 of 112 (70%) of groups A, C, W, X, Y, and Z strains. N. meningitidis strains which possess this epitope are immunotypes in which phosphoethanolamine (PEtn) is linked to the 3-position of the beta-chain heptose (HepII) of the inner core. In contrast, N. neningitidis strains lacking reactivity with MAb B5 have an alternative core structure in which PEtn is linked to an exocyclic position (i.e., position 6 or 7) of HepII (immunotypes L2, L4, and L6) or is absent (immunotype L5). We conclude that MAb B5 defines one or more of the major inner core glycoforms of N. meningitidis LPS. These findings support the possibility that immunogens capable of eliciting functional antibodies specific to inner core structures could be the basis of a vaccine against invasive infections caused by N. meningitidis.

Exploring the impact of perceived LMX variability within work teams

According to Leader-Member Exchange (LMX) theory, leaders develop different quaUt}' reladonships with the employees they supervise. To date, Utde research has invesdgated the impact of such differendadon by the leader on workplace outcomes. The current research proposes a novel way to capture the extent of LMX variabiUt}' within a single work team, and subsequently investigates the impact of perceived LMX variability on workplace outcomes. Across multiple employed samples, participants reported poorer team relations (as indicated by low team cohesion and high conflict) when they perceived LMX variability to be high. Perceptions of poor team relations further impacted negatively upon individual affect variables. The findings suggest that leaders may need to exercise caution when developing different quality relationships amongst individuals within the same work team.

The influence of communication sources on perceived risk about purchasing online

In this paper we report on a qualitative study into the influence of personal and non-personal communication sources in creating, sustaining and/or mediating people's perceptions of risk about purchasing online. In terms of non-personal communication sources, our findings suggest that the popular media significantly influence both purchasers and nonpurchasers’ perceptions of risk about using the Web for purchasing. Despite these negative perceptions, those who have purchased online appear to pay little attention to change agent communications on websites, such as logos, icons and statements about secure payment systems, which are designed to alleviate these concerns. In terms of inter-personal communication sources, our findings suggest that while there is evidence that to some degree, friends or peers influenced the interviewees about purchasing online, the purchasers in our study indicated that they would not influence others to do the same. We conclude our paper with suggestions for future interpretive research into the influence of communication sources on acceptance of the Web for purchasing.

Teaching Australian cello music to Intermediate students: An exploratory study of motivation through repertoire

This paper explores the motivational aspects of repertoire for intermediate student cellists. Research into interest and intrinsic motivation related to the learning of instrumental music has been limited to date. As a cello teacher interested in including contemporary and Australian music in my students' studies I started to research availability of Australian repertoire for intermediate cellists and found that there was limited accessibility to such pedagogical material at this level. This study emerged as a way of providing useful information to composers. It investigates intrinsic motivation by questioning students and their teachers about which aspects of music repertoire are most likely to inspire students to practice more and strive for excellence. This paper presents the findings of the purpose-designed questionnaire distributed to cello teachers in Queensland. A similar set of questions has been prepared for student cellists and information gathering from students is still underway. Musical aspects investigated include technique and its development, style, harmony, tempo (speed), and rhythm. The questionnaire gathered information on the most frequently used teaching repertoire and teachers' experiences in teaching contemporary and Australian repertoire. This information was balanced with questions regarding the technical developmental requirements perceived necessary for intermediate students as well as other motivational aspects. It is hoped that information collated from this research will be of benefit in the selection of motivational repertoire for intermediate student cellists and especially in promoting the composition of Australian pieces for intermediate cellists.
